The objective of this paper is to study behaviors of detention made by AISI1075 in
high temperature environment. The detention is used to hold the rocket until the
rocket launched. The rocket launched with salvo type. Therefore detentions get high
temperature from exhaust gas at 1,200 Celsius blow from rockets. There are the
criteria are selection and evaluation, the initial torque for tightening the detention arm.
In addition to avoid the failure of material and initially-tightened torque, the
understanding of the structural load on the detention is significant. As the initial
investigation, this paper presents the experiment test of detention including load
behavior on guide knob and on the detention arm. The initially-tightening torques for
the detentions were varied from 25 - 40 N.M. The results showed that detention made
by AISI1075 with initial-tightened torque 32 N.M. maintain the rocket with force
greater than 17,500 N. |
